This abstract describes a modification of the design criteria normally adopted for Offset Vector Tiles, so that they can be used more effectively with converted-wave data. The modification is based on the asymptotic conversion point correction and is a function of the Vp/Vs ratio. There are a number of potential applications of this approach in converted-wave processing. Here, we demonstrate the improvement that results in converted-wave prestack time migration of single offset vector tiles using this PS Offset Vector Tile design.
